60960628 divided by 406 
The aim is to understand the frequency of 406 in 60960628.

On to step 1:
The number 406 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 406

Let's proceed to step 2:
406 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 60 and we're left with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 406

Going ahead to step 3:
609 divided by 406 is 1 with a remainder of 203.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 406 from 609 to get 203.
Include the next digit (6) from the dividend after 203, then repeat: 2036 / 406

Moving on to step 4:
406 can be fit into 2036 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2030 from 2036 and we're left with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 406

On to step 5:
60 divided by 406 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
If we subtract 0 from 60, we get 60.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 406

Advancing to step 6:
If we divide 606 by 406, we get 1 and a remainder of 200.
Use 1 as the next digit of our solution. 
Result so far: 1501.0
If we take 406 away from 606, we end up with 200.
Append the next digit (2) from the dividend to 200 and continue with: 2002 / 406

Moving on to step 7:
If we divide 2002 by 406, we get 4 and a remainder of 378.
Use 4 as the next digit of our solution. 
Result so far: 15014.0
The remainder is 378 after subtracting 1624 from 2002.
Append the next digit (8) from the dividend to 378 and continue with: 3788 / 406

Step 8:
When dividing 3788 by 406, we get 9 with a remainder of 134.
The next digit of our result is 9. 
Result so far: 150149.0
Subtract 3654 from 3788 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 9:
The number 406 fits into 1340 3 times, leaving a remainder of 122.
Use 3 as the next digit of our solution. 
Result so far: 150149.3
Subtract 1218 from 1340 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Going ahead to step 10:
If we divide 1220 by 406, we get 3 and a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 150149.33
Subtracting 1218 from 1220 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 150149.33, with a leftover of 0.002.
